MACHINE FOR CLOSING SEAMS IN SHEET-METAL ROOFS.

SPECIFICATION forming part of Letters Patent No. 233,828, dated October 26, 1880. Application filed September 9, 1880. (No model.)

' To all whom it may concern:

Be it known that I, SAMUEL WooDHEAD, a citizen of the United States, residing at West Troy, Albany county, New York, have invented new and useful Improvements in Machines for Olosin g Seams in Sheet-Metal Roofs, of which the following is a specification.

My invention relates to machines for closing the seams of sheet-metal roofs preparatory to soldering down the same.

Prior to my invention it has been customary to hammer down the seams with mallets, which was a very laborious and tedious proceeding, causing not only great expense, but also incessant noise. To obviate this a machine was devised by which the seam was rolled down by means of a heavy metallic roller, said roller being guided by two wheels which straddled the seam. This machine, however, is somewhat complicated in construction, and can only be used to roll down a single seam at one operation.

The object of my invention is to overcome these obstacles and to enable the operator to roll two seams at the same time, and also to render the machine adjustable, as and for the purpose hereinafter set forth; and with these ends in view my invention consists of a heavy metallic or weighted body provided with axles and two heavy rollers or wheels journaled thereon, with collars adapted to be arranged ras hereinafter described, so that the distance between the wheels or rollers may be varied, in order that they may be adjusted to operate or less distance apart.

, My invention further consists in arranging P ,a system of pins on top of the body of the machine and mounting thereon a series of weights, in order that the weight of the machine and the consequent pressure by the rollers may be increased according to circumstances, and the machine rendered more portable, as will be presently explained.

My invention further consists in extending the body or frame of the machine rearward of the axle and forming it with a flat back and rounded lower corner, the handle the roller roof, as and for the forth.

in order that by lifting purposes hereinafter set may be lifted from the In order that those skilled may knowhow to make and use my improvement, I will describe its construction and operation, referring by letter to the accompanying drawings, form- 5 5 posed of cast-irou or other suitable material,

provided with axles B B, extending from each side or passing entirely through the body.

0 C are two rollers with suitable broad treads, adapted to roll down the seam or rib, and are mounted on the axles in position by collars D D and pins E. When the seams to be rolled are comparatively close together the rollers are placed close to the body or frame A and the collars D D arranged outside and between the pins E and the Wheels, 7 5

as shown in solid lines atFig. 2, and 'when it is desirable to arrange the rollers farther apart, as illustrated by the dotted lines, the collars are arranged on the axle and between the rollers and the body this adjustment of the rollers easy I extend the body A rearward of the wheels, the back being flat and the lower corner rounded, so that by slightly lifting the handle F of the machine the center of gravity is shifted behind the axles, the rounded corner. becomes a fulcrum, and the body may be turned up on its back, thus lifting the rollers from contact with the roof and sustaining them in position to be readily removed and adjusted, as shown by 0 dotted lines at Fig. 1.

In order that the machine may have its total weight increased, and at the same time be rendered portable, the top portion is east or formed with a step and provided with one or more posts or pins, G, adapted to enter holes in one or more'independent weights, H, which may be arranged thereon.

From this construction it will be seen that any number of weights or a given number of 100 different-sized weights may be employed, so that the aggregate weight of the machine Fig. 2 is a vertical section at the 60 B and secured 70 A. In order to render 8o may be varied according to the character of work to be performed, and that by reason of the removability of the weights the machine is rendered portable.

The frame and arrangement of weights are such that the center of gravity is, when the machine is in use, about in a vertical line passing through the axis of motion of the rollers.

I do not wish to confine myself to any particular contour or design as to the several parts, as they may be varied considerably without departing from the spirit of my invention.

WVhat I claim, and desire to secure by Letters Patent, is

1. In combination with the body Aand axles B, extended as described, the two rollers O O and collars D D, whereby the rollers may be adjusted, substantially as and for the purpose set forth. 2o

2. Thebody A, provided with pins Gr, adapted to enter openings in and support independent weights H, substantially as described.

3. The body A, extended rearward of the axle and having a rounded lower corner and 25 flat back, as described, whereby the rollers may be lifted from contact with the roof, substantially as and for-the purpose hereinbefore set forth.

In testimony whereof I have hereunto set 30 my hand in the presence of two subscribing witnesses.

SAML. WOODHEAD.
